An emanation system is described comprising and emanation device and a replaceable refill of liquid, wherein the refill comprises: a sealed reservoir of a liquid containing one or more active materials wherein the active material comprises at least one of: a fragrance; an insecticide; a fungicide; a pesticide; a sanitizing material; and/or a pharmaceutical; a porous wick having a length which extends from the interior of the reservoir to the exterior thereof; a reservoir seal having at least one aperture through which the porous wick extends; and a hollow liquid conduit housed within the wick having a length substantially identical to the wick; and wherein the device comprises: an air pump; a fluid conduit in fluid communication with the air pump such that, in use, air pumped by the pump will flow through the fluid conduit; a nozzle located at the end of the fluid conduit remote from the air pump; a ejector constriction provided in the fluid conduit adjacent or substantially adjacent the nozzle; a liquid conduit engaging member provided adjacent the ejector constriction and in fluid communication with the fluid conduit at one end thereof, and configured at the other end to, in use, engage the hollow liquid conduit in the refill; characterized in that a mechanism is provided to permit the liquid conduit engagement member to form a liquid tight seal with the liquid conduit.

Devices for improved delivery of volatile liquids

An emanation device for use with a replaceable refill of volatile liquid containing one or more active materials is described wherein the active material comprises at least one of: a fragrance; an insecticide; a fungicide; a pesticide; a sanitizing material; and/or a pharmaceutical; wherein the refill comprises a sealed reservoir containing said volatile liquid and a porous wick which extends from the interior of the reservoir to the exterior thereof, wherein the device comprises: an air pump; a fluid conduit in fluid communication with the air pump such that, in use, air pumped by the pump will flow through the fluid conduit; a nozzle located at the end of the fluid conduit remote from the air pump; a ejector constriction provided in the fluid conduit adjacent or substantially adjacent the nozzle; a liquid conduit provided adjacent the ejector constriction and in fluid communication with the fluid conduit at one end thereof, and open at the other end to receive liquid therein; refill securing means configured to secure the refill relative to the device; characterized in that a mechanism is provided to permit the liquid conduit to at least partially penetrate the porous wick.

Devices and methods for improved delivery of volatile liquids

An emanation device is described which comprises: a replaceable refill of liquid containing one or more active materials wherein the active material comprises at least one of: a fragrance; an insecticide; a fungicide; a pesticide; a sanitizing material; and/or a pharmaceutical; wherein the refill comprises a sealed reservoir containing said volatile liquid and a porous wick which extends from the interior of the reservoir to the exterior thereof; and wherein the device comprises: an air pump; a fluid conduit in fluid communication with the air pump such that, in use, air pumped by the pump will flow through the fluid conduit; a nozzle located at the end of the fluid conduit remote from the air pump; a ejector constriction provided in the fluid conduit adjacent or substantially adjacent the nozzle; a liquid conduit provided adjacent the ejector constriction and in fluid communication with the fluid conduit at one end thereof, and open at the other end to receive liquid therein; characterized in that the liquid conduit is located within the porous wick.

An emanation system is described comprising and emanation device and a replaceable refill of liquid, wherein the refill comprises: a sealed reservoir of a liquid containing one or more active materials wherein the active material comprises at least ona of: a fragrance; an insecticide; a fungicide; a pesticide; a sanitizing material; and/or a pharmaceutical; a porous wick having a length which extends from the interior of the reservoir to the exterior thereof; a reservoir seal having at least one aperture through which the porous wick extends; and a hollow liquid conduit housed within the wick having a length substantially identical to the wick; and wherein tha device comprises: an air pump; a fluid conduit In fluid communication with tha air pump such that, in use, air pumped by the pump will flow through the fluid conduit; a nozzle located at the end of the fluid conduit remote from tha air pump; a elector constriction provided in the fluid conduit adjacent or substantially adjacent the nozzle; a liquid conduit engaging member provided adjacent the ejector constriction and in fluid communication with the fluid conduit at one end thereof, and configured at the other end to, In use, engage the hollow liquid conduit in the refill.
